IMPRovnD PIPE-correa l The" Schedule referred to in these Letters Patent making partof the same.

Be it known their, Anstoss e. WILDER, bf. on;

i hoes, in the connty'of A1bany, and State of New York,

have invented a new and improved Pi`peO ut-ter;" and I do hereby declarethat the following is a full, clear,

and exact description of the `same,-reference being hereby had to the` accompanying drawings, which form and make a part of this, my specification.

"Like letters represent and refer to like or corresponding parts.

Figure 1 is'a perspective view of my improved lpipecutter, showing the different parts thereof more fully hereinafter described and, set forth;

Figure 2 is a cross-section', ,showing the screw-ham die, knife, and springkrnore fully hereinafter described Figure 3 is an enlarged perspective view of the knife, cylinder, containing spring, and end of sc rewhandle, showing ythe relative position of each, as more fully hereinafter set forth; and

` f Figure 4 is a section ,through the cylinder containing the spring, and showing the same,iwhich is used in connection with the knife and screw-handle, in the manner and. for the purposes hereinafter. fully described ble piece of rubber, or other elastic substance, placed between and in combination with the screw-handle f and the knife or cutter, whereby or by means whereof, f the knife or cutter is Aallowed to give, and pass over any inequalities or hard substance in the pipe or tube being out, substantially as hereinafter more fully described and set forth. f f

It also consists in the use and employmentpof a screw-handle, in combination with a spring, of suitable elastic substance, and a knife or cutter, all ar- It also consists in the use of adjustable rollers or supports, fastened to Vthe upper part of the metallic frame of my said pipe-cuttenforthe purposeof guiding and clamping the pipe or tube to be out, andy the said rollers are made adjustable, so as to conform to different sizes `of pipe, substantially as more fullyhere iuafter described and set forth. Y f

` -To enable others skilled in the art to'which my in- A, figs. 1 and 2, is the body or frame of Vimproved pipe-cutter, and may be made of any metal'deemed best, and in as many parts as` desired, `but I prefer to ranged and combinedin the manner and for the pur-j cast the same in one solid Apiece o f malleable or castiron, andY of such size and strengthas I may desire.

This .frame A has a core or opening throughthe lower part of the same, as shown at iig. 2, the upper part ofwhich opening has a thread out therein, which thread corresponds with the thread Son the screwhaudle Bz This screwhandle B is a metal rod of any length and strength required, and is for the purpose of regulating and working the knife or cutter O, ashereinafter morefully described.-

D, figs. 1 and 2, is a hard .piece of wood or other.

material, fastened to the outer end of the saidv screwhandle B, and is for the purpose of aiding in working the same, as hereinafter described.

The knife or cutting-tool O, figs .1, 2 and 3, is made of steel, andA may be of any shape and size deemed best to use, but ismade at its upper end of a size and shape'to correspond with-the upper part of the slot or core in the frame A, and itsl closely in the same, as seen at iigsL l'andv 2. A

Between this knife or cutting-tool() and the screwhandle B, and inthe core 'or slot in the frame A, I

place a coiled spring, or a piece of hard rubber or other elastic substance, of suitable sizeand shape, marked E in the accompanying drawings, and shown atfigsl, 2 and 3. f

Iprefer to enclose this coiled spring or elastic substance in a metal drum or covering, F, fig. 4, and cover thesame with a cap, G, same figure, so as to give stability and firmness toSaid--spring E, the knife G resting against the top of said drum, and the screw-handle B resting against the cap G, which cap G is made of metal and fits loosely on the inside of said drum F, and

a, shown at figs. 3 and 4.

The rollers or supports H H, &c., I design to make is prevented from being forced out by the ange'or riml of any metal deemed'best to, use, and they are fastened to the upper part of the frame A by means of the screws b b, iig. 1.

The upper part of saidfrarne Amay be slotted or pierced with holes, as seen at iig. 1, whereby, and by means vi/hereof, the said rollers or supports, H and H, may be adjusted to support any size of pipethat the `said frame A will admit into thel opening K, figs. 1

and 2.

The manner of operating my said machine is as fol# lows, to wit:4 The pipeortubeto be cutis placed iu the frameA through the opening K, resting between the rollers H and ,H and the knife C. The said `knife O is then screwed down close to the pipe by-means of the screwhandle B and hand-piece D.A The Wholefdevice or pipe-cutter isthen turned or made to lrevolve once around the pipe or Vtube .being cut, afterwhich thev knife is again screwed down, and the operation described continued until the pipe or tube is completely `severed .or cut into. Should the knife C encounter any hard substance or`ineqna1ity iu the pipe, it will give back, by means of the spring E, and pass over the same. If desired, the knife O may be removed at any time, and be sharpened or repaired.

By the means Vand in the manner hereinbefore described, I am enabled to construct a pipe-cutting tool which, for durability and cheapness, exceeds any like machine now in market.

Having thus described the nature of my said invention,

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. The arraugement'of the knife or cutting-tool C and the spring E, operated upon by the screw-handle B, and in combination with the adjustable rollers H CHARLES D. KELLUM 7 JAMES DALY.
